The current study was designed to investigate the effects of 1-(1,3-benzodioxol-5-yl-carbonyl) piperidine (1-BCP) on swimming endurance capacity which as one indicator of fatigue in the weight-loaded forced swimming mice. Mice were given either vehicle or 1-BCP (0.1, or 0.2 mmol/kg body weight daily) by intraperitoneal injection once daily for 2 weeks. The 1-BCP groups showed a significant incr...

A rapidly aging global population has motivated the development and use of models for human aging. Studies on aging have shown parallels between zebrafish and humans at the internal organization level; however, few parallels have been studied at the whole-organism level. Furthermore, the effectiveness of exercise as a method to mitigate the effects of aging has not been studied in zebrafish. We...

We tested the influence of temperature and water velocity o n metabolic rate and swimming performance of lake whitefish (Coregonus dupeaformis) and cisco (C. artedii) using respirometry techniques. Tests were conducted at 5,12, and 1 P C (speed range 20-102 crnss-'f for lake whitefish and at 12°C (speed range 20-63 cm-s-') for cisco. Fish lengths ranged from 10 to 33 cm (TL). The net aerobic co...

Metabolic rates of aquatic organisms are estimated from measurements of oxygen consumption rates ( ) through swimming and resting respirometry. These distinct approaches are increasingly used in ecophysiology and conservation physiology studies; however, few studies have tested whether they yield comparable results. We examined whether two fundamental measures, standard metabolic rate (SMR) and...

Wylegala J, Schafer-Owczarzak M, Pendergast DR. Optimization of fin-swim training for SCUBA Divers. Undersea Hyperb Med 2007; 34(6):431-438. Underwater swimming is a unique exercise and its fitness is not accomplished by other types of training. This study compared high intensity intermittent fin-swim training (HIIT) with moderate intensity continuous (MICT). Divers (n = 20; age = 23 ± 4 yrs; w...

BACKGROUND Methylnicotinamide (MNA) displays vasoprotective activity, however, the regulation of the activity of nicotinamide-N-methyltransferase (NNMT), is largely unknown. We analyze a possible involvement of IL-6 in the activation of NNMT-MNA pathway during an endurance exercise. METHODS FVB, C57Bl/6J IL6(+/+) and C57Bl/6J IL-6(-/-) mice were subjected to the single bout of endurance exerc...

We followed up swimming performance times of 321 women and 319 men who participated in the US Masters Swimming Championships over a 12-yr period. All swimmers placed in the top 10 in their age group over 3 yr (mean = 5 yr). A random coefficients model for repeated measures was used to derive a line of best fit from a group of regression lines for each subject. Both 50- and 1,500-m swimming perf...
